Title: Keying system for electric musical instruments
IPC: G10H5/07
Filed: 1962-08-24
Abstract: 1,024,562. Electrophonic musical instruments. D. H. BALDWIN CO. Aug. 24, 1962 [Aug. 28, 1961], No. 32249/62. Heading G5J. [Also in Division H3] A keying circuit for an electrophonio musical instrument comprises a diode 3 in a loop comprising a tone generator 1, a condenser 2 and an output system 4. An exciting circuit, which may include a bias battery 7, a switch 9 and a resistor 10, enables the diode to transmit the tone. The diodes may be gas discharge tubes, solid state rectifiers, or vacuum tubes. Arrangements for producing percussion tones, chime tones and carillon tones are described.  Decay control, Fig. 4.-Closure of switch 17 connects condenser 16 to the resistors 10, 14 and lengthens the time constant of the biasing circuit for diode 3. The decay time is shortened by closure of switch 20. Battery 21 has a voltage substantially the same as the breakdown voltage of discharge tube 18. Tube 18 breaks down when switch 9 is closed and the voltage at point 15 drops to zero, which is the control voltage at which diode 3 ceases to conduct. There is a delay controlled by capacitor 2 and resistor 10 before the diode 3 cuts off. Percussion, chimes and tone synthesis, Fig. 6 (not shown).-A single key may operate a resistance-coupled gradual-contact key switch 31, to feed a fundamental frequency from generator 1c to a filter 29 and may also operate a switch 9c to enable diodes 3c, 3d, 3e to feed the fundamental and harmonies from generators 1c, 1d, 1e to filters 37 etc. By operation of stop switches 38, 39 etc. the fundamental and harmonies may be selected and fed to the output system 41. By operation of stop switch 40, the fundamental and harmonies are passed by a resistive summing network to a filter 36 and an output network 41 giving a chime or carillon type tone. The resistance-coupled key switch provides touch control of attack, decay etc. The control circuits of diodes 3c, 3d, 3e may incorporate features of Fig. 4. The resistancecoupled key switch 31 may be replaced by make-and-break switches arranged as in Fig. 3 or Fig. 4. Self-bias and diode leaks.-When switch 9, Fig. 4, or 9c, Fig. 6 (not shown), is open any current flowing through diodes 3 or 3c, 3d, 3e tends to build up back bias and to prevent further flow of direct current but the capacity of the diode may permit transmission of an attenuated tone signal. To stop this leak, diodes may be used in pairs such as 56, 59, Fig. 8 (not shown). Between the diodes, a resistor 61 and a capacitor 62 provide a shunt path to ground for any leakage current. In Fig. 8, the generator may generate a square wave. The key controls a resistive-coupled switch 66 feeding a filter 68 and a make-and-break switch feeding a circuit like Fig. 4 to control the diodes 56, 59. Square wave generator.-Multivibrators using transistors may be used as frequency dividers. Each stage serves as a generator for the instrument. A complete percussion system for an organ as illustrated in Fig. 11 (not shown).
